Steps to reproduce the problem:
I got to try the Pixel Slate today and it's fantastic but I did come across 1 website that required a trackpad/mouse. Microsoft's tablets had the same problem and they solved it by adding a virtual/on-screen trackpad to Windows 10 and it's perfect, Chrome OS needs this for the Pixel Slate because it uses the full/desktop user agent, it doesn't use a mobile user agent (thank goodness!)

What is the expected behavior?

What went wrong?
Here is Microsoft's announcement of the virtual trackpad, scroll down to the section titled "Controlling external monitors from tablets just got easier"

Did this work before? N/A 

Chrome version: 70  Channel: stable
OS Version: 70

I really hope to see this added soon, it will allow Pixel Slate owners to leave the keyboard at home without having to worry (or if they just forgot to bring the keyboard)
